7/14/2013 - I typed this and had it ready to go except for adding the quote marks above - that zapped me! SO....
McAfee called me again yesterday (7/13/2013) and set up an appointment with me for trying a fix next Thursday morning (7/18/13) . I do not know whether to be hopeful or not! I will update this discussion after that time with the results. Prior to this (same day) Apple Sr Tech emailed me with thiis:
"Good Afternoon Jane,
I've been reviewing the information you gave me and I see the issue you are describing is happening to others but I'm not sure if you understand what I meant when I was trying to tell you the cause. I believe what the forums are stating maybe correct. Almost every person on that forum having the issue is also using McAfee. There is more than likely some conflict between the two programs, but if that is the case it would not be Apple to resolve the issue because iTunes is not the cause. iTunes works fine on all other devices McAfee is causing the issue as it is only those machines who seem to be affected. "
I DID let him know again that AVG and some other programs had the same issue. So as you can see Apple is not really taking any responsibility with iTunes being any of the cause! CJ Green
